Abstract:
In this research, the properties of charcoal briquettes from
cassava stems were studied. and using tapioca starch, sodium silicate
and water as a binder By doing an experiment to find the right ratio for
making charcoal briquettes. The test was divided into 2 parts by 2 types
of binders: Part 1 Charcoal from cassava stems using cassava starch as a
binder. It was found that the optimum ratio was charcoal : cassava
starch : water which was 1000 : 120 : 2000 (g unit : g : ml) and part 2
charcoal briquette from cassava stem using sodium silicate as binder. It
was found that the optimum ratio was activated charcoal : sodium
silicate : water, which was 1000 : 400 : 1500 (unit g : ml : ml). Tapioca
Starch Compared with sodium silicate, it was found that the cassava
starch binder has better properties due to its high calorific value of
5258.34 cal/g and low moisture content of 6.71%, which makes the
briquettes combustible. Comply with community charcoal briquette
product standards (MorPhor.Chor. 238/2547)
